CONNECTION TO SUPERVISION SYSTEM

(EXTERNAL SUPERVISOR SYSTEM
SOLUTION)
Connection is possible for version External
Supervisor System 3.10 or higher.
Using serial port RS485 it is possible to connect FWECSA
controllers (up to 247) to a management software that uses
standard MODBUS RTU as a communication protocol, with
the following characteristics:
• settable baudrate (defualt: 9600);
• no parity
• 8 bits of data
• 1 bit of stops
Inside a supervision network, each FWECSA controller acts
as a SLAVE towards the centralised management system
which constitutes the network MASTER (figure 01).
Once the network has been wired, it is necessary to configure
each FWECSA controller. Press PRG to access the MENU
and then enter sub-menu "Networks and connections"
(password = 20). Set the SETUP RS485 parameters as
follows:
• MST/SLV = "Slave from SPV"
• Protocol = "Modbus"
• Serial address = set a value between 1 and 255
• Speed = set based on the requirements of the Master
leave the SETUP OC PARAMETERS UNCHANGED (MST/SLV
= none).
For details on how to wire the network, read
"RS485 NETWORK GUIDE LINES" available in
the download area of the Daikin website.
